Why are some English Teachers worse than others?

There are a lot of English language students out there who find learning English to be a really difficult task, and who are not happy with there teachers.

The main cause of student frustration is that the majority of English Teachers here are crap. Most of the teachers have a good command of the language (Although there are many who don't) but they have no idea of how to teach. This is especially true of 'Native speaking' teachers.

Often, Colombian English Teachers, who had learnt English in the United States, Canada, England, or are graduates of a Colombian Bilingual' High School, are not much better, and have forgotten how difficult it is to learn English, and get frustrated with the students, adding to the students' anxiety.

Smegged off? You Bet!
